Forgive the horrible title. It vaguely describes the issue/ problem. This isn't really a bug, more a failure of the feature.
If you join a live stream in progress, Whether 5 minutes or 55 minutes into a show, and wish to start watching from beginning by using the rewind feature on the time bar. However, Once the show finishes and http://www.giantbomb.com/chat/ changes to 'the There is currently no show' page the live stream that you are watching with a time delay stops and the page auto-refreshes to the 'the There is currently no show' page.
It would be nice to be able to watch the delayed live stream to completion, but i'm sure there is some technical limitation as to why this isn't possible.
